Never wished the Flea were bigger. Smaller, yes, lots of times.
I moved to the west coast once, all my stuff crammed in a 1989 Honda Accord without too much trouble. And once to the east coast, Firefly packed to the headliner. I kind of like the way a smaller vehicle makes you re-evaluate how much stuff you really
need .
The ForkenSwift is another story. It's just right - I use it a fair amount to take a pair of nephews and our snowboards/sleds to the local park to play in the snow. If I couldn't fit three and our gear, it'd mean going in a gas-burner.
